BARBi-:D wiRE FOR FENCES.

SPECIFICATION forming part of Letters Patent No. 268,721-, dated December 5, 1882.

4 Application filed September 2.", 1882. (No model.)

To all whom tt may concern:

3e it known that I, JOHN P. OSTERMAN, of the city of Joliet, in Will county, and State ot' Illinois, have invented certain new and useful Improvements in Barbed Wire for Fences, the construction and operation ot' which I will pro- .ceed to explain, reference being had to the annexed drawings and the letters and figures thereon, making a part of this specitication, in which- Figures 1 and 2 are perspective views. Figs.

` 3, 4, 6, and 7 are views ot' the barbs detached "strand-wire of the fence, provided at intervals along its length with the S-shaped bends shown in Figs. l, 2, and 5. For convenience, the S-shaped bend has its two bends lettered w" and w, respectively. The S-shaped bend iu the strand-wire fw is so placed that the line ofthe strand-wire would pass through its center. The barbs are made of wire, and their pfecular form is shown in Figs. 3, 4, 6, and 7, and

are denominated right7 and left barbs, as shown in the said figures. The said barbs, in ordertobe placed on the strand-wire w, are bent around and inclose the S-shaped bend in the strand-wire, as shown in Figs. l and 2, the

said ligures being reversed, so it will be more easy to trace the course ot' each barb. rlhe barbs are placed 01| said bend in pairsright and left. By reference to Fig. 2 it will be observed that barb a is bent around to inclose the S-shaped bend of the strand above barb c', and has one ol' its prods a pass through .the loop w" of said bend, to prevent the S- shaped bend in t-he strand from being pulled out straight by tension on the strand and to assist in holding the barb on. Barb cis bent around the said S-shaped bend in asimilarmanner below barb c', and its prode passes through the opposite loop, w', ot', the said S-shape'd bend. The opposite prods ot'either of the said barbsare bentoutward from the strandatright angles, or nearlyso,with the strand w, as shown.

The form of thebarbs shown in Figs. 6 and 7 shows their bends a little llonger than those in Figs. 3 and 4, so'they may inclose more ot' the S-shapedbend in the strandwire, ifdesircd. The forms shown in said Figs. 6 and 7 are the forms that are probably the most practicable to use. By this construction lt'our barbs or prods are provided at a place, forminga very strong, cheap, and effective barbed wire.

Having thus described in v invention, what Iclaim as new, and desire to secure by Letters Patent, is as follows, to Wit:

ln a barbed wire for fences, the wire strand w, having the S-shaped bend described, on which the twin barbs a and c are placed, so as to lie on a parallel line with each other and on a diagonal line with the wire strand w, and having the prods a and c passed under' the bends w and to, to prevent the S-shaped bend from straightening and to assistin holding on the barbs c and a', in the manner set forth.A JOHN 1. OSTEEMAN.
